I recommend looking at the definition of scene kids if you don't know what they are yet.

A Scene Cunt (yes, it's capitalized) is a girl that takes part of the Scene society. Scene Cunts are typically 14 year old girls who think being Scene is a competition; most of them believe that they are original and anyone who steals their hairstyle will die (even though 30 million other girls look exactly the same).

Scene Cunts tend to spend a lot of their time on Myspace and Buzznet; most of the time, they will only accept friend requests from people who look like they're worth a damn.

Person 1: I tried requesting some girl on Myspace to be my friend the other day, but she messaged me back saying she only befriends "beautiful people".
Person 2: What did you say back to her?
Person 1: I called her a Scene Cunt and told her to blog about it.
